Oops, I forgot that used qtruby too.

Grep for the name 'x_QByteArray' in the sources that were generated for your 
version of the Smoke library:

baldhead duke 831% grep 'class x_QByteArray' *.cpp
x_1.cpp:class x_QByteArray : public QByteArray {

That would mean the Smoke lib is too new for the version of qtruby you have.
